We all know that Kamen Rider EX-Aid has reached it mid-season with the debut of his newest super form, Kamen Rider EX-Aid Maximum Gamer Level 99 so let's start some new Rider series rumors starting with the "leaked" image above.
According to Kamen Rider news, the japanese text says "2017 New Kamen Rider Plan # 1 Maguro Form Body" and it also claims that it came from PLEX as seen in the title.

As usual folks, take this with a grain of salt. Could we be having another Kamen Rider Gaim in our midst with this Edo period design after EX-Aid ends.
